EJECTOR-BLADE FOR LINOTYPE OR ANALOGOUS MACHINES.

SPECIFICATION forming part of Letters Patent No. 614,582, dated.November 22, 1898.

Application filed December 31, 1897. Serial No. 665,043. (No model.)

To all whom, t may concern:

Be it known that I, ODDUR VIGFS SI- GURDSSON, a subject of the Queen ofthe United Kingdom of Great Britain and Ireland, residing at Manchester,England, have invented certain new and useful Improvements in theEjector-Blades for Linotype and Analogous Machines, (for which I have0btained a patent in Great Britain and Ireland, No. 9,384, dated May 1l,1894;) and I do hereby declare that the following is a full, clear, andexact description of the invention, reference being made to theaccompanying drawings, which are to be taken as part of thisspecification and read therewith,and one which will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in the ej ector-blades of linotypesand analogous machines; and the object of it is to obviate the necessityof changing the blade each time that the mold in the machine is changedfor one of a different size, especially for one of a smaller size. i

Linotypes or printing-bars vary in respect of two dimensions-theirlength and their thickness-and the ejector-blade of a linotype-inachinefor pushing the linotype out of the mold in which it is cast isconstructed according to my invention in such a Way that i it can bemodified in respect of both the said dimensions, as distinguished fromreplacing it by another, and that, too, Without detaching the Wholeblade from the machine.

In carrying the invention into effect a bar (which may be thinner andshorter than the blade) is provided. It is made fast by one end to theejector-carrying slide or equivalent ejector carrying the operatingdevice in such a Way that .it shall stand Within the plane of the travelof the said blade. The bar in question is hereinafter referred to as thestock A supplemental plate is provided for each size of mold to extendor fill out the stock to the proper dimensions of the ejectorblade, assuch dimensions may be required to Work in such mold. Each plate isslotted longitudinally, the slot allowingit to embrace the stockedgewise and stand in the same plane With it. When it is in thisposition,

the plate end :tits up to the ejector-head and the nose of the stock upto the internal end of the slot.

The plates above mentioned are of Various Widths and of variousthicknesses along their noses, according to the lengths and Widths,respectively, of the mold-cavities. erative thickness of a plate mayextend for only a short distance back from the nose or front edge of it,the remaining portion in the case of all the plates of the series beingof one normal thickness thinner than the said nose or front edge.

A modification of the invention allows the plates and stock to be of auniform thickness and the plates to stand parallel with the stockinstead of embracing it.

Any suitable device may be used to hold a plate to the stock in theplane of it and to lock it to the said stock. I propose that the plateshall be held in the plane of the stock by suitable side guides and byfeathers and tenons on either the stock or the plate adapted to engagein or with respectively corresponding parts on the other of them. Aplate is locked to the stock by spring lingers or hooks retractable intothe. plate or into the stock by any suitable means and adapted toautomatically engage edge on into the other of them. l l

The essence of the invention lies in an ej ector Which may be enlargedor diminished in cross-section to suit different molds by theapplication to or removal of supplemental blades or sections used inconnection With the main blade or stock.

Referring to the accompanying drawings, which are to be taken as part ofthis specification and read therewith, Figure l is a side elevation ofan ejector-blade made according to the present invention. Fig. 2 is aplan of the same. Fig. 3 is a side elevation of the opposite side of theejector-blade illustrated in the preceding gures. Fig. 4 is a sideelevation 4of the ejector-blade stock. Fig. 5 is a side elevation of thedetached plate. Fig. 6 is an inverted sectional plan taken on the line 66 of Fig. 5. Fig.' 7 is a vertical section taken on the line 7 7 of Fig.5. The foregoing seven figures illustrate also one and the same devicefor holding the plate to the stock. Fig. 8 is a side elevation of anejector-blade The opsa crasse made according to the present invention,but modified in respect of the shape of the plate, the position of thestock on the head, and the device for holding the plate to both. Fig. 9is a plan of the same. Fig. 10 is a vertical section taken on the linel0 lO of Fig. 8. Fig. ll is a side elevation of the detachable plateillustrated in the three preceding figures. Fig. l2 is a side elevation,and Fig. 13 a plan, of a modified form of the present invention,according to which the plate is as long as the stock and both of thesame thickness throughout.

Referring to Figs. l to 7, a is a plate by which the present inventionis incorporated with the ejector-head. By the latter term I mean thefront end of the ejector-slide. This plate a may be of any suitableshape and the means for incorporating it with the said head may be ofany suitable type. Convenience suggests that it be rectangular in shapeand of the proportions shown, and be held to the ejector-head by meansof screws or holdingpins passed through holes a. This plate a is, toprevent confusion of ideas, hereinafter referred to as the head-plate.

l) is the stock. lt is a bar made in one piece with the head-plate, fromwhich it projects at right angles. It is to be noticed that it does notproject from the middle of the head-plate, but from near one end of it.The last-mentioned end corresponds with the head of the line,which headmay be considered as a constant, the shortening or lengthening of aline, due to change of front, showing itself at the other end. Assumingthat the maximum diiference in length of line is one-half the length (orheight, looking at the drawings) of the head-plate a, then must thestock be set well within the dimensions of the shortest line. The stockis shorter than the ejectorblade. By ejector-blade is to be understoodthe combination oi stock b and plate (1,., next described.

c is one of the series of plates with which each ejector-head isprovided. A full series of plates is one for each size of mold used inthe machine. Each plate has a longitudinal slot c formed in it of theexact size of the stock ZJ and at such a distance from its bottom edgec2 that when the plate is made to embrace the stock in the plane thereofthe said bottom edge will be alined with the bottom edge a2 of thehead-plate u, and its back edge c3 iit close up to the front edge a3 ofthe said head-plate.

The width of the plate o corresponds with the length of the cavity ofthe corresponding mold, and the thickness of it with the width(thickness of the linotype) of the said cavity. It is not absolutelynecessary that the plate c and the stock h should be as thick throughoutas the mold-cavity is wide. It is enough if the leading or front edge clof the plate c possesses the proper thickness. Such possession isclearly illustrated in Figs. l, 2, 3, 5, G,

lt is obvious that the practical utility of the invention cannot beenjoyed unless proper provision be made for holding the plate' c and thestock b (then, the ejector-blade) together in one and the same plane andfor separating them when an ejector-blade of a different size isrequired. The present invention does not limit me in respect of eitherthe type or the details of the said provision. That illustrated may beaccepted as practically sufficient for the purpose. It consists of thesteadying and the locking devices. The steadying devices are tenons c5c5, with mortises a4 a4 at one end of the plate c and a tenon b' andmortise c6 near the other. The tenons c5 are on the back edge c3 of theplate. These tenons have beveled rear edges. The mortises a3 are all onthe same side of the head-plate a and in the front edge of it. Further,they are undercut to receive each beveled edge, above mentioned, so thatwhen the tenons c5 are engaged in their respective mortises aAL there isa steadying contact in each engagement between four surfaces. The tenonb projects from the front end of the stock b and engages in a mortise cGopposite to it in the front end ot' the slot c.

The locking device illustrated is as follows:

d is a bolt. It is a thin iiat bar adapted to work in and out of alongitudinal slot d', formed in the plate c half-way between its sides.This formation is conveniently ef fected by removing the necessaryquantity of material and fixing a coverplate (Z2 over the resultingcavity.

(Z3 is the pivot of the bolt. It stands at right angles with the sidesof the plate c.

d" is the bolt-staple. It is a sloping groove cut in the top edge of thestock l), parallel with the sides of the latter. The position of thebolt Z is so arranged in the plate c that the bolt-staple clL shall beat some appreciable dis tance behind the front end of the stock.

el is the bolt-spring.

(ZG is a slot through the plate c and through which the end of the boltd always shows. Through this end there is a hole (Z7. The width of theslot d is sufficient to allow of the unlocking motion of the bolt, whichis effected by inserting the pointed endof any suitable lever in thehole d? and raising it.

The plate c is xed to both the stock Z) and the head-plate a by slidingit longitudinally from the front over the stock and in the plane of ituntil the bolt CZ locks into its staple d4. Then the bolt has beenunlocked, the plate c is detachable from the stock and head-plate.

Referring to Figs. S to 11, the stock b projects from the head-plate aat the bottom of it instead of from near the end. Consequently the slotc of the construction illus trated in Figs. l to 7 becomes alongitudinal rabbet c7. The locking device is an angular tooth e,projecting from the bottom edge of the plate c and in the plane of it.Its front edge is preferably vertical. e is a notch of correspondingcontour in the top edge of the stock Z1 and in the plane of it, in whichnotch.

IIO

the tooth e is adapted to t. The plate c is fixed to the head-plate aand stock h in the way already described, the tooth e sliding over theside of the stock on its way to the notch c. As soon as the engagementsbetween the tenons and mortises are completed the tooth is opposite thenotch and is sprung into it by the natural resilience of the plate c.The latter is unlocked by pushing the tooth c out of the notch e'laterally. In al1 other respects the improved ejector-blade illustratedin Figs. 8 to 11 is the same as the one illustrated in Figs. 1 to 7 anddescribed therewith.

Referring to Figs. 12 and 13, the modification consists in making theblade c as long as the stock ZJ and both of the same thicknessthroughout. The locking device is of the same construction asillustrated in Figs. 1 to '7 and described therewith.

1. In a linotype-machine, an ejector, adjustable in size, comprising incombination, a main blade or stock, asupplemental blade, and means forlocking said blades together.

2. In an ejecting mechanism for linotypemachines, an ejector consistingof longitudinal blades or sections, and means substantially as describedfor longitudinally lookin g them together.

3. In a linotype-ejector, a main ejector blade or stock, in combinationwith an auxiliary blade applied to its longitudinal edge,and

locking devices, substantially as described, holding the auxiliary bladein position and permitting its removal at will.

4:. In a linotype-machine and in combination with a main ejector-blade,an auxiliary blade, arranged to engage therewith at the two ends, andlocking devices, substantially as shown, to maintain such engagement.

5. In a linotype-ejector, the combination of a main ejector blade orstock, an auxiliary blade, arranged to interlock therewith bylongitudinal motion, and a latch or bolt, mounted in one of said membersand engaging the other, substantially as described and shown.

6. In a linotype-ejector, the combination of the main ejector blade orstock, c1. b, and the auxiliary blade, c, arranged to engage therec withat the two ends, and a spring-actuated latch-bolt, d, entering the edgesof the two blades substantially as shown.

7. In a linotype-ejector, the combination of a main ejector blade, orstock, and a detachable blade or section, having its operative end ofdifferent thickness from that of the main blade.

In witness whereof I have hereunto affixed my signature, in presence oftwo witnesses, this 17th day of June, 1896.
